This removal has led to a necessary refactoring:
- make the setup of field attributes extensible;
- make the instantiation of custom fields extensible;
- delegate model and field reflection to `ir.model` and `ir.model.fields`;
- move the implementation of sparse and serialized fields to module `base_sparse_field`;
Before this revision,
using a selection field with as possible keys `0`,
such as `require_payment` in `website_quote`,
resulted to the records field values to be stored
as `NULL` instead of `0` in the database.
This leads to the inability:
- To distinguish records with this selection field not set
or set to `0` (as both are stored as `NULL`)
- To search for records with the field set to `0`
(as they are considered not set)
For instance, while having `website_quote` installed,
search for sales orders with `Payment` set to
`Not mandatory on website quote validation`: It won't
return any result, even if you have some.

The dictionary `_group_by_full` is replaced by a field parameter `group_expand`
that is assigned to the method name. The API of the method has been simplified
as well:
@api.multi
def _read_group_stage_ids(self, domain, read_group_order=None, access_rights_uid=None):
# the stages are given by self.ids (wrong model);
# read_group_order is the order given to read_group() on self;
# return stages.name_get(), {stage.id: stage.fold)
_group_by_full = {'stage_id': _read_group_stage_ids}
is now written:
stage_id = fields.Many2one(..., group_expand='_read_group_stage_ids')
@api.model
def _read_group_stage_ids(self, stages, domain, order):
# stages is a recordset;
# order is the order to use on stages' model;
# return a recordset which is a superset of stages
